Electron wake is the disturbance left after a high-energy charged particle passes through condensed matter or plasma. Ions passing through can introduce periodic oscillations in the crystal lattice or plasma wave with the characteristic frequency of the crystal or plasma frequency. Interaction of field created by these oscillation with the charged particle field alternate from constructive interference to destructive interference, producing alternating waves of electric field and displacement.

  • Electron wake is the disturbance left after a high-energy charged particle passes through condensed matter or plasma. Ions passing through can introduce periodic oscillations in the crystal lattice or plasma wave with the characteristic frequency of the crystal or plasma frequency. Interaction of field created by these oscillation with the charged particle field alternate from constructive interference to destructive interference, producing alternating waves of electric field and displacement. The frequency of the wake field is deterrmined by the nature of the penetrated matter, and period of wake field is directly proportional to the speed of the incoming charged particle. Amplitude of the first wake wave is most important, as it produces braking force on the charged particle, eventually slowing it down. Wake fields also can capture and guide light ions or positrons in the direction perpendicular to the wake. The larger the speed of the original charged particle, the larger the angle between initial particle's velocity and captured ion's velocity.
